RATIONALE: Giving combination chemotherapy and total-body irradiation before a peripheral stem cell transplant that uses the patient's or a donor's stem cells, helps stop both the growth of cancer cells and the patient's immune system from rejecting the stem cells. When the stem cells are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Giving combination chemotherapy and total-body irradiation followed by a stem cell transplant may be an effective treatment for anaplastic large cell lymphoma.
